Man has always been at war.  This book goes all the way back to our family tree; before us the chimpanzees, relatively peaceful as we know them now.  However, our prehistory forebears were warlike as evidenced by spearheads found embedded in their bones.  When they took up growing gardens and crops they fought over protecting their rights. Religious warfare began over God's Promised Land to the Israelites and they killed the Canaanites over the rights to the land that God gave them. That land is in dispute to this day.  Our Native American Indians lost their lands to the European colonists moving west and bringing them diseases that killed most of them.  The worst fighting ever was in World Wars I and II.  Millions and millions of people killed at immense dollar cost.  Nations that start wars are seldom winners. Now we have upon us a new kind of Terrorism, and today it's all about fundamental Islamic beliefs.  The United Nations needs to be stronger if we are to have peace in the world.   Steven C.
